Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transfer paper made using an ink jet method.

It is well known that dyes of the sublimation, vaporization, and thermal melt transfer type, conventionally called sublimation dyes, can be used in transfer techniques, and their use is becoming more widespread year by year.

However, conventionally, most transfer papers have been used to form images using printing methods that require plates, such as gravure printing and offset printing.

However, in these gravure printing and offset printing, the plates themselves are expensive, and the images that can be formed are substantially limited by the size of the plates that can be created. For example, a 5 meter long eel streamer design cannot be substantially formed using these methods. In order to avoid this drawback, a method of forming an image by a screen printing method using an endless metal stencil plate is also being researched.

In this method, since a long metal endless plate is guided by several rollers for printing, it is possible to create an image of approximately the same length as the stencil plate that can be produced, for example, one repeat of 10 meters. . However, in order to make the metal stencil plate endless, both ends of the stencil plate are joined by a method such as melting after being installed on the printing machine, so that the images on both ends are not misaligned and are aligned in the appropriate direction by the tensile force of the roller. Difficult to connect as it is pulled. Furthermore, products with large images are usually produced in relatively small lots, but for the reasons mentioned above, the price per product is inevitably high. Furthermore, by any of the above methods, it is virtually impossible to form an image having a long length in the vertical and horizontal directions, for example, an image of 3 meters square.

The present invention was made in view of these circumstances, and
The purpose is to provide a transfer paper with a large image at a low cost, and to provide a transferred product with a large image at a low cost. In particular, it is desirable to apply the present invention to small-lot products. That is, in the present invention, when a transfer paper is created by an ink jet method using an ink containing a sublimable dye, a part of the desired image is formed on each of a plurality of temporary supports, and then the obtained This is an ink-jet type transfer paper that is characterized by forming a desired image by appropriately joining together a plurality of temporary supports.

The ink jet method used in the present invention refers to the direction and amount of ink ejected from the nozzle by applying a high voltage between the nozzle and an electrode installed in front of the nozzle according to the original or other signals. There is a method commonly known as ink jet printing that controls the size of the nozzle and the pressure applied to the nozzle to control the amount and direction of ink jetting to form an image.

It also includes a method called spray. Therefore, in order to obtain the transfer paper according to the present invention, no printing plate is required, and photosensitive photographic paper, developer, etc. accompanying the preparation of the printing plate are not necessary, and no plate-making work is required.

Furthermore, it is possible to freely enlarge or reduce the same original, and an image of any size can be obtained easily and quickly. Furthermore, as mentioned above, ``transfer products with large images are usually produced in relatively small lots, but the transfer paper of the present invention can be produced in large numbers even in small lots, for example, even when the purpose is just one transfer product. For example, if you are looking for 1,000 or more transfer products, you can obtain the product at a unit price that is not much different from that of the other product.

Furthermore, since the present invention is produced by the above method, it is possible to easily and quickly produce a transfer paper having an image having a long length in both the vertical and horizontal directions, for example, an image 3 meters square. .

The sublimable dye that can be used in the present invention may have a molecular weight of 100 to 25,000 and can be transferred by sublimation, vaporization, or thermal melting.
Specifically, cationic dyes (including old basic dyes), such as Eisenkatilon Yellow 33LH, Eisenkatilon Brilliant Yellow 5GLH, Eisenkatilon View Your Full - 50 Days (all dyes manufactured by Hodogaya Chemical ■),
Diacrylic Red Y F (dye manufactured by Mitsubishi Kasei ■), Methyl Violet (C.1.42535), Crystal Violet (C.1.42555), etc., and disperse dyes such as Diacrylton First Pink B, Diacryl Tonph These include Earth Pink R (dye manufactured by Mitsubishi Kasei ■), Sumikalon Red FB (dye manufactured by Sumitomo Chemical ■), and the like.

Solvents that can be used to make inks suitable for ink-jet printing using sublimable dyes are water, monohydric alcohols, and ethylene glycol, ethylene glycol monoethyl ether, diethylene glycol, diethylene glycol monoethyl ether, and triethylene. These are polyhydric alcohols such as glycol, triethylene glycol monomethyl ether, tetrac monoglycol, propylene glycol, polyethylene glycol (molecular weight 200 to 600), polypropylene glycol (molecular weight 400 to 2000), glycerin, and derivatives thereof. Furthermore, a binder and the like are added as appropriate, and a low viscosity liquid with a specific ps of 4 to 1 at 2000 is used as an ink. The material used as the temporary support is usually paper, and paper whose surface is coated with a substance that has good transfer color development and transfer efficiency, such as dextrin, is preferable.

The objects to be transferred, that is, the transferred products, include fibers such as natural fibers, semi-synthetic fibers, and synthetic fibers, resin-molded products, resin-coated boards, anodized aluminum boards, etc., depending on the sublimation dye used. Any material that can be dyed is fine.
